Can You Run Your AC without a Filter?

Can You Run Your AC without a Filter?

This is a question we hear often. In some cases, excessive heat and the inability to get a replacement filter fast leaves home and business owners facing intense heat or running their AC without a filter.

In situations where you MUST run the AC unit, you can do so without a filter for a limited period of time (6-8 hours maximum). However, if this can be avoided you should wait until you can get a replacement at the store or through an HVAC service.

The Importance of an AC Air Filter

Your AC unit brings in outdoor air, removes heat and moisture from the air, then blows it back into your home or business. The air filter acts as the first line of defense against a broad range of particulates present in that air. It actively filters out pathogens such as bacteria, mold spores, pollen, dirt, pollutants and more.

When you run your unit without the filter, these particulates make their way into the system and eventually spread throughout your home.

Negative Impact of Running your AC Without a Filter:

  • Reduced indoor air quality and health concerns
  • Dirty/dusty home or business
  • Damage to the AC’s compressor
  • Frozen evaporator coils
  • Increased wear and strain on the system
